It has just ruined 2/3 of my work. Please please fix it!!!
if i read you correctly, you were working on a file which was previously saved/named (the other 1/3 of the work)… is this correct?
if that’s the case then rhino saved the other 2/3 upon closing… have you re-opened the file?
or- are you saying you’ve reopened the file and the work wasn’t saved? if so, that IS a problem but i’ve personally never seen that happen before.
do you understand how OSX versioning works?
